Abstract

L'invention porte sur un dispositif électronique, comportant un circuit imprimé souple (FPC), reliant électriquement un premier connecteur à un deuxième connecteur pour empêcher le FPC de se détacher, sans devoir recourir à un composant additionnel ou à un connecteur de structure spéciale, et formé entre un premier côté du FPC inséré dans le premier connecteur et le deuxième côté du FPC inséré dans le deuxième connecteur de manière à être dévié vers un élément distant du premier et du deuxième connecteur, et s'étendant le long du premier connecteur et du deuxième connecteur, jusqu'à ce qu'il entre en contact avec ledit élément. Le FPC présente une rigidité grâce à laquelle, lorsqu'il est poussé par ledit élément suite à son contact avec ledit élément, le premier côté et le deuxième côté sont poussés dans la direction d'insertion du premier connecteur et du deuxième connecteur.
